  ...
  3. If Type(P) is String, then
    a. Let numericIndex be ! CanonicalNumericIndexString(P).
    b. If numericIndex is not undefined, then
      i. Let buffer be the value of O's [[ViewedArrayBuffer]] internal slot.
      ii. If IsDetachedBuffer(buffer) is true, throw a TypeError exception.
      iii. If IsInteger(numericIndex) is false, return false.
      iv. If numericIndex = -0, return false.
      v. If numericIndex < 0, return false.
      vi. If numericIndex ≥ the value of O's [[ArrayLength]] internal slot,
